John was very professional. To my surprise John had video. John had a written report and he served my paperwork in a timely fashion. John even returned the paperwork back to me in a timely fashion. John's work was so good that he isn't aware that new charges will be pressed on the parties involved in another case by the Westchester County Police. Yes I would use John again if I ever have another issue like this again and will refer him to all others that have issues with family court and more.
